Embodiment 1

[0044] (1) Weigh raw materials: Weigh 33 grams of hexamethylene diisocyanate trimer (Desmodur N3300A), 94 ml of polar solvent acetone, 3.53 ml of deionized water, and 0.6% by mass of alkali Sex catalyst triethylamine (Triethylamine);

[0045] (2) Mixing: First, mix the hexamethylene diisocyanate trimer and acetone weighed in step (1) evenly, then add deionized water to the mixed solution, then add the basic catalyst triethylamine, and mix evenly;

[0046] (3) Post-processing: Stir the mixture obtained in step (2) uniformly with a magnetic bar stirrer for 10 minutes, then let it stand for 1 hour to form an airgel, and inject the airgel into a polypropylene plastic mold to form and dry An airgel material is obtained.

[0047] The density of the airgel material prepared in Example 1 is about: 0.33g / cm 3 , is a high-density airgel material.

Embodiment 2

[0049] (1) Weigh raw materials: Weigh 17 grams of hexamethylene diisocyanate trimer (Desmodur N3300A), 94 ml of polar solvent acetone, 1.5 ml of deionized water, and 0.2% by mass of alkali Sex catalyst triethylamine (Triethylamine);

[0050] (2) Mixing: First, mix the hexamethylene diisocyanate trimer and acetone weighed in step (1) evenly, then add deionized water to the mixed solution, then add the basic catalyst triethylamine, and mix evenly;

[0051] (3) Post-processing: Stir the mixture obtained in step (2) evenly for 10 minutes with a magnetic bar stirrer, and then let it stand for 3 hours to form an airgel, and inject the airgel into a polypropylene plastic mold to form and dry An airgel material is obtained.

[0052] The density of the airgel material prepared in embodiment 2 is about: 0.17g / cm 3 , is a medium-density airgel material.

Embodiment 3

[0054] (1) Weigh raw materials: Weigh 7 grams of hexamethylene diisocyanate trimer (Desmodur N3300A), 94 ml of polar solvent acetonitrile, 0.2 ml of deionized water, and 0.05% by mass of alkali Sex catalyst triethylamine (Triethylamine);

[0055] (2) Mixing: First, mix the hexamethylene diisocyanate trimer and acetone weighed in step (1) evenly, then add deionized water to the mixed solution, then add the basic catalyst triethylamine, and mix evenly;

[0056] (3) Post-processing: Stir the mixture obtained in step (2) evenly for 10 minutes with a magnetic bar stirrer, and then let it stand for 12 hours to form an airgel, and inject the airgel into a polypropylene plastic mold to form and dry An airgel material is obtained.

[0057] The density of the airgel material prepared in embodiment 3 is about: 0.07g / cm 3 , is a low-density airgel material.

[0058] figure 1 It is the electron micrograph of the airgel material prepared in Example 1.

Abstract

The invention discloses an aerogel material. According to performance parameters of the aerogel material, the average hole diameter ranges from 5 nm to 80 nm, the specific surface area ranges from 5 m<2> / g to 300 m<2> / g, the density ranges from 50 kg / m<3> to 500 kg / m<3>, the coefficient of thermal conductivity ranges from 0.018 W / mK to 0.060 W / mK, the porosity ranges from 60% to 99%, the water absorptivity is less than 5%, and the liquid adsorption capacity is 5-15 times of gravimetric absorption. The aerogel material is good in liquid adsorption capacity and has excellent slow release performance, liquid release speed is uniform, liquid release time is long, and the aerogel material is safe, has no toxic or side effects and can be widely applied to slow release materials of parasiticides or perfume.

Description

technical field [0001] The invention relates to an airgel material and its preparation method and application, in particular to an airgel material with high-efficiency liquid adsorption capacity and long-term uniform slow-release ability, its preparation method and application, belonging to chemical materials technology field. Background technique [0002] In the application of perfume release, most of the existing perfume crafts are composed of balsam material and solvent. Generally, the smell of perfume is relatively strong at the beginning, but gradually fades or even disappears as the solvent emits fragrance. Lasting fragrance is also between 2-3 hours. Prolonging the volatilization time of perfume and maintaining the lasting release of fragrance is the focus of current perfume technology research, and it is also the demand of consumers. [0003] Application No. 200710061694.X discloses a long-lasting perfume. In this invention, propylene glycol is added as a thickener...
